The cost of 6 bags is GH¢ 210

The cost of 11 bags is GH¢ 385
GH¢245.00 can buy 7 bags

Tens bags cost GH¢350.00

one bags cost = 350/10

= 35

The cost of 6 bags can be calculated as follows

1 bag= 35

6= x

cross multiply both sides

x= 35×6

x= 210

The cost of 11 bags can be calculated as follows

1= 35

11= y

cross multiply

y= 35 × 11

= 385

The number of bags  GH¢245.00 will buy can be calculated as follows

1 = 35

x= 245

cross multiply both sides.

35x= 245

x= 245/35

x= 7

Hence GH¢245.00 can buy 7 bags, 6 bags cost GH¢210 and 11 bags cost  GH¢ 385

When x increases the value of f(x) decreases called decreasing function thus the interval on which the function is decreasing is  (-∞, -5] ∪ [-2, 2].

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given graph of a random function,

The value of f(x) decreasing when x is increasing is the interval on which we can say that function is decreasing.

If we look at the extreme left of the graph and come towards the right then the curve is going downward till x = -5.

Therefore, in interval (-∞, -5] function is decreasing.

The function is again going down in intervals [-2,2].

Therefore in inteval  (-∞, -5] ∪ [-2, 2] the function is decreasing.

Hence "When x increases the value of f(x) decreases called decreasing function thus the interval on which the function is decreasing is  (-∞, -5] ∪ [-2, 2]".

The value of x is 21

The other angles are 63°, 117°, 63°, 117°

Given:

The angles of a parallelogram ABCD are

∠A = 3x°

∠B = (5x+12)°

To find:

The value of x

Parallelogram ABCD,

∠A and ∠B are two adjacent sides

Properties of a parallelograms

Two opposite sides are parallelogram are equal and parallel to each other.

So, the adjacent sides are supplementary angles i.e. sum is 180°.

The opposite angles are equal.

Now,

∠A + ∠B = 180°

⇒ 3x + (5x + 12) = 180

⇒ 3x + 5x + 12 = 180

⇒ 8x + 12 = 180

⇒ 8x = 180 - 12

⇒ 8x = 168

⇒ x = 168 ÷ 8

⇒ x = 21

Thus,

The value of x = 21

The angles are

∠A = 3x = 3 * 21 = 63°

∠B = (5x + 12) = (5 * 21 + 12) = 105 + 12 = 117°

As opposite angles are equal so

∠A = ∠C = 63°

∠B = ∠D = 117°

Explanation:

The ratio of bananas to tomatoes can be calculated as the division of the number of bananas in the recipe over the number of tomatoes in the recipe. So, the ratio is:

Therefore, to find the simplest form, we can divide the numerator and denominator by 2 as:

Then, we can fill the table as:

Bananas Tomatoes Ratio

1 3 1/3

2 6 2/6 = 1/3

3 9 3/9 = 1/3

4 12 4/12 = 1/3

Where every ratio is equivalent to 1/3

Answer:

N^2+6 is in standard form, which is in ax^2+bx+c,

in order to get it to vertex form, which y=a(x-h)^2+k, we need to find the vertex, through x=-b/2a, in this case:

x=-0/2(1)=0, so h=0, then plug 0 in for n,

0^2+6=6,

which makes k=6,

therefore, the answer is c.

as for a, the value of a is constant in all forms, whether standard, vertex or factored, making a=1

The value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3

What is slope of a line?

The slope of a line explain the steepness of the line segment. It is ration of the coordinates of the y-axis and the vertical coordinates of the x-axis. Depending upon the slope value, it is classified as whether lines are parallel or perpendicular.

According to the question, the given parameters for the line segment is as written below:

Slope of a line = (-4) and the coordinate points = (-1, 7)(x,-9): (x1 = -1; y1 = 7)

Now, by using standard equation for the line segment: y = mx + c

where, 'm' is the slope; c is the y-intercept; (x, y) are coordinates

Substituting given values that is slope and y-intercept in the standard equation, we get:

y = mx + c

⇒ 7 = (-4)(-1) + c

⇒ c = 7 - 4 = 3

Therefore, the value of the y-intercept is: c = (3)

Equation of the line by substituting the value of the y-intercept as well as slope value in another equation whose coordinates are (x, -9):

-9 = (-4)x + (3) ⇒ -12 = -4x ⇒ x =3

Hence, the value of the variable 'x' is calculated by solving equation of the line by using slope value is: x = 3

The perimeter of the figure is 22.4 cm, and The area of the figure is 30.2cm²

The Pythagorean theorem, or Pythagorean theorem, explains the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to Pythagoras' theorem.

From the diagram, the formation is a rectangle.

Use the coordinate points to find the measurements of each side.

Side length AD = Side length BC

Apply the Pythagoras connection to find length BC as;

a² + b²= c² where a=2 cm and b = 4 cm and c =BC

2² + 4² = c²

4+16 = c²

20 = c²

c= √20 = 4.4721

Length BC = Length AD = 4.5 cm

Side length AB = Side length DC

Apply the Pythagoras connection to find the length DC as;

a² + b²= c² where a=6 cm and b = 3 cm and c =DC

6² + 3² =c²

36 + 9 = c²

45 = c²

√45 = c

c= 6.7082

c = DC = 6.7 cm

Now you have the dimensions of the rectangle as;

Length = 6.7 cm and width = 4.5 cm

The perimeter will be ;

P= 2{l +w} --------- where l is length and w is width and P is the perimeter of the rectangle

P=2{6.7 + 4.5}

P=2{11.2}

P= 22.4 cm

The area will be ;

A= l*w

A= 6.7 * 4.5 = 30.15 = 30.2 cm²

The perimeter of the figure is: 22.4 cm

The area of the figure is: 30.2 cm²

The value of P = $5000, r = 3.6%/4 = 0.9%, n = 4n and amount after 10 years is $5450.

Compound interest may be defined as the interest which can be applied by any institution on any individual in which the interest amount after a year becomes principle for the next year. The formula for compound interest is given as A = P(1 + r/n) ^ nt where A is the amount, P is the principle, r is the interest rate, n is compounding frequency and t is the time. If compounded quarterly the principle will be same as in the question that is $5000, the interest rate will be divided by 4 that is r = 0.9% and the compounding frequency will be 4 times that is 4n. Now, we need to find the amount after 10 years that is t = 10 years. The amount will be

A = P(1 + r/4n) ^ 4nt

A = 5000(1 + 0.9/100×4×12) ^4×12×10

A = 5000(1.09)

A = $5450 which will be amount after 10 years.

Answer:

A. 4+(-4),

D. -9+9​

Step-by-step explanation:

A expression has a sum of 0 when we have two equal numbers with inverse signals.

A. 4+(-4)

We have the same number(4), and they have inverse signals. So this expression has a sum of 0.

B. 6.3 +(-3.6)

6.3 and 3.6 are different numbers, so this expression does not have a sum of 0.

C. 13+(-11)

13 and 11 are different numbers, so this expression does not have a sum of 0.

D. -9+9​

We have the same number(9), with inverse signals. So yes, this expression has a sum of 0.

We are given that an inch is approximately 1.57828x10⁻⁵ mile.
